Title: Unselective electrode for determination of ionic concentrations in solution
IPC: G01N27/403
Filed: 1979-10-29
Abstract: The invention provides an electrode for use in determining the total concentration of tree ions in a test solution, the electrode having the property that the variation of its electrode potential with the logarithm of the sum of the free ion concentration-mobility products of electrolyte solution in electro- chemical contact therewith is linear with an intercept and slope which are constant for a given temperature and pressure, and the electrode being unselective and not distinguishing between different free ions. The electrode comprises a reference electrode R, preferably Hg/Hg2Cl2/Cl<-> or Ag/AgCl/Cl<->, in contact with a special solution 4 which in turn contacts the test solution, both contacts preferably being via liquid junctions 3,5. The special solution 4 is a solution of at least one strong electrolyte having a pH close to neutral and with mobility or weighted mean mobility of its cation(s) significantly different from that of its anion(s). One such electrode and another such electrode or a reference electrode form a cell whose constants are obtainable experimentally and from whose measured p.d. the sum of the concentration-mobility products of the free ions of the test solution is obtainable. From this sum the free ion concentration in the test solution is calculated or approximated. Measurement of test solution pH allows adjustment to be made for the presence of H<+> and OH<->. <IMAGE>

Patent GB-2070937-A (GB)
Title: Heart stimulating apparatus
IPC: A61N1/37
Filed: 1980-03-11
Abstract: A demand-type heart pacer can be operated in a fixed rate test mode and includes a synchroniser 4 operative to synchronise the start of the fixed rate mode to occurence of a spontaneous heart beat, thereby reducing the chance of a test rate stimulating pulse occuring during the vulnerable T-wave period. The test mode is selected by an external device 1, eg. magnetic, electromagnetic, acoustical, optical or piezoelectric. If the test mode is selected between two spontaneous beats 31, 32 (Fig. 3), synchroniser 4 responds to beat 32 to inhibit heart beat sensing circuit 6 and to cause pacer timing circuit 5 to generate stimulating pulses 33, 34 at a fixed higher-than-normal rate, the first such pulse 33 occurring at the fixed rate interval after beat 32. When a predetermined number, eg 2, of fixed rate pulses have been generated, synchroniser 4 causes timing and sensing circuits 5, 6 to revert to normal demand operation. If the request for the test mode is still being applied, synchroniser 4 causes the start of a further sequence of the predetermined number of fixed rate pulses 36, 37 to be synchronised to the spontaneous beat or demand-generated stimulating pulse 35 next following the last pulse 34 of the previous test rate sequence-this operation repeating until the test mode request is removed. Sequencer 4 may have CMOS circuitry, including a shift register to count the predetermined number of pulses (Fig. 4). The pacer can be used to terminate tachya rhythmias by applying a stimulating pulse in the diastolic period of the heat beat and repeating such pulser, or required, at predetermined intervals, the pulser being synchronised with the spontaneous heart beats. <IMAGE>
